When the valve stem 24 is reciprocated, nuid will be pumpedfrom the container I1 to the compartment I2. On each up stroke o! thepiston 2| fluid will be drawn through the inlet 28 and on each downstroke the valve 29 will close against the valve seat 20 so that thefluid is forced out through the outlet 35.

The container I1 is provided with a removable screw closure Il throughwhich liquid may be supplied thereto. A support bracket II is interposedbetween the container I1 and the body Ill and handle I8. This supportbracket serves as a foundation for an electric switch 42 for controllingthe electricity to the iron. The supply of current is obtained throughthe cable 4l.

A valve l5 is located above the top end of the pipe Il and is supportedon a rod I6 which is slidabiy mounted in a bearing I1. This rod 46 isprovided with a flange Il against which an expansion spring 49 acts.This expansion spring also acts against the top of the body I and servesto normally urge the rod 4B into a raised position so that the valve l!is opened. The upper end of the rod I6 is disposed immediately adjacentthe arm III. A block 49' is attached within the handle I8 and serves tolimit flexing of the arm 20. The arm 2|) may be ilexed by forcing thelever I9l to axially move the stem portion I9", and then the arm 20 willassume the position indicated by the dot and dash lines 20' in Fig. 2.

While the lever I9* is held in this position it may be simultaneouslypressed downwards so that the arm 2li strikes the top of the rod 46 andmoves the rod downwards. The valve 45 is thus brought into contact withthe top of the pipe I6 which is formed into a valve seat. In thiscondition the passage between the compartment I2 and the channel I! isclosed. Consequently, water and steam within the compartment I2 will begiven an opportunity to build up a pressure. Then when the lever I9* isreleased the valve l will be opened by the spring I9 and the highpressure steam discharged through the channel I5 and the perforationsII.

In Fig. 8 a slightly modified form of the invention is disclosed whereinthe cylinder 2l of the pump is disposed completely within the containerI1. The radial arm 2l* is shorter so that it is located completelywithin the container I1. It is connected with the upper end ,of the stem24. In other respects this form oi' the invention is identical to theprevious form and corresponding parts may be identified by the samereference numerals. The pipes 2l and 35 are formed with curved portionsto act as traps.

While we have illustrated and described the preferred embodiments of ourinvention, it is to be understood that we do not limit ourselves to theprecise constructions herein disclosed and the right is reserved to allchanges and modmcations coming within the scope of the invention asdefined in the appended claim.

Having thus described our invention what we claim as new and desire tosecure by United States Letters Patent isz- In combination with a steampressing iron having a body, a heating element in said body, a chamberin said body in thema] conductivity with said heating element, a waterreservoir supported by said iron, a pump for forcing water from saidreservoir to said chamber whereby steam may be generated when said ironis heated, said chamber having an outlet pipe. passages connecting saidoutlet pipe to the bottom of the iron to allow steam to pass to thework. and a member for actuating said pump normally in one position butshiftable to another position, valve means for closing said outlet tobuild up steam pressure in said chamber, and a valve actuating elementattached to said valve means and selectively engageable or not with saidpump actuating member in its shifted position whereby said valve meansor, said valve means and said pump, together. may be selectivelyactuated by a single operation.
